Seems dongle hardware failure. If you have another dongle try it.

If you don’t have another dongle try these:

  • un-plug and re-plug dongle, then reboot Pi
  • if using USB cable to connect dongle to Pi, remove it and connect dongle directly to Pi
  • test dc voltage by following command (if command gives no output, then voltage is ok)
    sudo dmesg --ctime | grep voltage

Didn’t have replacements but did the unplug replug. Also - was using both freq and just did 1090 for now. Working great now. thanks for the help.
